Great visualization! Is it based on https://distill.pub ? See, e.g., https://distill.pub/2017/momentum/

You are right. Another detail is to find a metric which is meaningful in long term, e.g., the one which is in line with long-term happiness of your customers.

I guess it is up to you to define your metric to be measured and to be optimized. To define the right metric and targets is not easy and probably is business-specific, i.e., is not the same for every business.

I am wondering if it is based on their own Google HyperTune / Vizier [1, 2] which is modified to better deal with uncertainties or it is an absolutely independent in-house development. [1] https://cloud.google.com/ml-en

Thank you for providing useful references. Hyperparameter tuning can accelarate CPLEX by 10x and more depending on problem instances (however, it it true that each new version of CPLEX is faster and faster). What I meant is that in the case

You may formulate it as a multi-objective problem where you minimize the estimated time of the trip and your uncertainty of this estimate. Often, the two objectives are conflicting. As a user, the software should show you a Pareto set of op

You can use heuristics if/when the problem becomes ugly due to various constraints you may impose. The trick is to select heuristics depending on the problem at hand and in a way that their hyperparameter values are selected properly.

Spearmint has quite a few practical drawbacks so I guess that both Vizier and SigOpt are much better by now.

I think that in the context that he meant, 64 variables = 64 hyperparameters because it was about benchmark problems solved in black-box settings. In other words, it is not about the common misconception of comparing #hyperparameters and #

Whetlab was the first startup in this domain. Then, followed by SigOpt ( https://sigopt.com/ ) which is doing a great job at popularizing the concept.

Thanks for reporting! The site is hosted on Google Cloud Platform. If some of GCP's IPs are banned in your company, then it might be the reason.
